To all wii om it may concern.

Be it known that I, Fnnonmon M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating on Shoe-Soles; and. I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for operating on the marginal portions of shoe soles.

In the manufacture of shoes of the well known Goodyear or welted shoe type, inaccordance with. a process recently devised, the outsole is temporarily secured in position on the shoe bottom preparatory to stitching the same to the welt by cementing the mar ginal portion of the outsole to the welt. In this process a coat of cement having been applied to the marginal portion of the outsole, or to the welt, or to both, the outsole is placed on the shoe bottom and located improper-position relatively thereto, and the welt and the marginal portion of the outsole are then pressed firmly together to caiise the same to adhere. The same procedure may be followed in the manufacture of other types of shoes in cementing the marginal portion of. an outsole to the sole portion of a shoe secured to and projecting beyond the body of'the upper.

The primary object ofv the present invention is to produce a machine by which the operation of pressing together the marginal portion of an outsole and the welt or other sole portion of a shoe projecting beyond the upper in cementing the same together may be performed in a rapid, eflicient and reliable manner.

Vith the above object in view, an important feature of the present invention consists in the provision of two sets of pressing devices for engaging and pressing together the marginal portion of an outsole and a sole portion of a shoe secured to and'projecting beyond the upper arranged to act simultaneously and progressively on opposite sides of a shoe as the shoe is fed past said devices, With machine embodying this feature, the above operation may be performed upon both sides of a shoe at the same time with a resultant saving of-considerable labor and time of the operator.

The shoe may be fed past the pressing devices by the movement imparted thereto by the operator. Preferably, however, the shoe is fed automatically by the. machine so as to relieve the operator of unnecessary labor in subjecting the shoe to the operation of the machine. In the present machine the feeding mechanism is constructed and arranged to control at all times the feeding movement of the shoe, thereby insuring a uniform movement of the shoe past the pressing devices. In the particular construction illustrated in the present application the pressing devices operate intermittently to grip the marginal portion of the outsole and the projecting sole portion of the shoe between them, and the two sets of said devices are actuated alternately to feed the shoe.

Other features of the invention consistof certain novel and improved constructions, arrangements and combinations of parts hereinafter described and particularly pointed cut in the claims the advantages of which will be readily understood and appreciated by those skilled in the art.

The features of the invention will be clearly understood from the accompanying drawings illustrating a machine embodying the invention in its preferred form and the following detailed description of the con structions therein shown.

In the drawings Figure 1 is a plan view partly in section of a machine embodying the invention; Fig. 2 is a view in front elevation partly broken away and partly in section illustrating the rear portion of the machine; Fig. 3 is a view partly in side elevation and partly in section illustrating certain parts of the mechanism shown in Fig. 2; and Fig. 4 is a detail view in front elevation illustrating one set of pressing devices and certain associated parts.

In the construction illustrated in the drawings each set of pressing devices comprises a support 2 shaped to enter the crease between the upper and the welt or other sole portion of a shoe secured to a d p O JERSEY, A CORPORATION OF MACHINE FOR OPERATING ON SHOESOLES.

tion of the shoe, eachsupport 2 1s secured jecting beyond the upper and a beater 4 arranged to engage the marginal portion of an outsole applied to the shoe bottom. To enable the supports to conform to the transverse curvature of the projecting sole porto the upper end of a shaft 6 mounted to turn in a bearing 8 formed in an arm of a carrier 10. The supports are each yieldlngly held normally in position with the work engaging surface thereof substantially parallel with the work engaging surface of the corresponding beater by means of a coiled spring 11 attached at one end to a collar 12 secured to the lower end of the shaft 6, and at its other end to a pin mounted in an a'rm 13 on the carrier 10. The heaters 45 are preferably made of yielding material such as rubber so that they will readily conform to the transverse curvature of the outsole.

Each beater 4 is rapidly reclprocated toward and from the corresponding support 2 during the operation of the machine and exerts intermittently a yielding pressure on the marginal portion of the outsole, thereby pressing the same firmly into contact with the projecting sole portion of the shoe. To

' enable the beaters 4 to yield when engaged with the marginal portion of the outsole each beater is secured in'a slide lt mounted to slide in guides in an oscillatory arm 15 and is acted upon by a coiled spring 16 surrounding a rod 18 to which the slide 1 f is secured, the spring being interposed be tween the slide and the upper end of the guide-way therefor in the arm 15. The movement of the slide under the influence of the spring 16 is limited by the engagement of a nut 20 threaded on the upper end of the rod with the arm 15. Each of the arms 15 is pivoted 'on the corresponding portion of the shoe engaged between the support and the beater of each set. The shoe is advanced rearwardly between the two sets of pressing devices which move relatively away from and toward each other during the rearward movement of the shoe so as to follow the contour of the shoe at all times. To enable the sets of pressing devices to move relatively .so. as to follow the contour of the shoe. each of the carriers 10 is provided at itsrear end with spaced arms embracing a supporting block 24: and is pivoted upon bearing pins 22 pas ing through the arms of the carrier and gripped between the corresponding sup threaded into the supporting block. Each supporting block is carried by guide blocks 25 mounted on a shaft 26 to turn about said shaft. The shaft 26 is journaled in bearings 27 carried by suitable arms on the frameof the machine and constitutes the. main shaft of the machine from which the movingparts are actuated. This'manner of mounting the carriers enables the sets of pressing devices to swing toward and from each other in planes containing the axis of the main shaft 26. The carriers also can swing about the shaft 26 to enable the sets of pressing devices to move vertically to conform independently to the transverse curvature of the shoe bottom. In order to support the carriers verticall the frame is formed with su) ortin arms 28 arranged to engage abutment faces formed on the carriers.

The carriers are connected by a coiled spring 30 which constantly tends to swing the carriers toward each other. During the movement of the shoe between the supports 2 the spring 30 through its action on the carriers maintains these supports constantly inengagement with the upper of the shoe. These supports thus act as guides and through the cooperative action of the supports and the spring 80, the pressing devices are caused to follow the outline of the shoe. The swinging movements of the carriers toward each other under the action of the spring 30 is limited by the engagement of a stop projection 32 formed on each carrier with the'side of the corresponding arm 28.

With the two sets of pressing devices arvranged in the manner above described, the

shoe may be fed rearwardly between the same by the operator to cause said devices to act progressively on the parts of the shoe from the toe toward the heel thereof. In the present construction, however. the'pressing devices are actuated to feed the shoe. .Vhen the beater 4tof one set of pressing devices is engaged with the outsole, the marginal portion of the outsoleand the projecting sole portion of the shoe are securely rt 2 and the beater, and when the beater is disengaged from the outsole the shoe is free to be moved rearwardly relatively to the set of pressing devices. Each set of pressing devices is reciprocated forwardly and rearwardly in timed relation to the movements of the corresponding heater to feed the shoe,

the rearward movement of each set occurring while the parts of the shoe are gripped between the heater and the support 2, and the forward. movement thereof when the beater is disengaged from the outsole. The feeding movements of the two sets of pressing devices occur alternately. one set being moved rearwardly to feed the shoe while the other set is moved forwardly, so that a substantially constant rearward feeding ing devices. The forward? and; rearward movements are imparted? to the two. sets: of I pressing deviceeby mechanism: acting. to reciprocate: thecarriers: 10:1ongitudi'nally:

The eccentric block is thus held from turning movement relatively to the block 24 and? to the carrier 10; To enable forwardandirear- -Ward reciprocatingmovements to be im- 25 parted to each of the carriers 10, each of the supporting blocks 24 is mounted to slide on 'the corresponding guide blocks 25, and; to

this end each supporting block isformed with parallel guide-ways in which therespective guide blocks therefor engage. The vertical movements impartedto the eccentric blocks 44 by'the eccentrics 46: through the connections describedi will impart oscil- -latingmovements to thenbeater supporting 35 arms 15. The forward: and; rearward movements of the eccentric blocks. through the engagement ofthe. guide arms'48 with; the blocks 24 will, impart forward and rearward movements to saidblocksand tothe carriers 10. The two eccentrics46 are mounted on the shaft so that the carrierslO will be alternately moved forwardly and rearwardly, these movements of the carriers occurring intimed relation to the movements of the respective arms 15 sothatthepressing devices will act alternately to; grip andyfeed the shoe rearwardly.

The driving mechanism'for. the main shaft 26 comprises a driving clutch: member 52 mounted to turn loosely on theshaft; and to receive a suitable driving belt, and a driven clutch member 54 secured: to the outer: end

of the shaft. The driving clutch member-52 is: also movable longitudinally of the shaft 26 to carry the same into and out of engage ment with the driven clutch member54, and is normally held out of engagement, with the latter clutch member by a coiled spring 56; The driving clutch;member 52 isgadapt ed to be moved longitudinally of the shaft 26 into engagementwith the, driven; clutch member 54 by meansof, a vertically movable clutch operating wedge 56 interposed; be-

positions shown inf Fig. 1. With the parts inthe relative positions shown in this'figure,

be separated readily by the rearward movement of the shoe. To enable around or blunt toed shoe to be inserted between the supports 2 in position to start the operation,

mechanism arranged to be actuated from the treadle is provided for moving the carriers 10 relatively away from each other to separate the supports 2. In the illustrated construction this mechanism is arranged to be actuated to separate the supports 2 by the movement of the treadle before the clutch is engaged to start the machine. This mechanism comprises a wedge 80 adjustably mounted on the upper end of the rod 68 and "arranged to engage anti-friction rolls 82 mounted on arms; 84: formed on the carriers 10; In order to' guide the wedge 80, the

wedge is formed on its rear side with a rib which engages between guide flanges project- 1 taneously and progressively on opposite ing from an arm 85 on the frame and the wedge is provided with a slot 86 in which engages a shouldered screw 88 threaded into the arm 84. As illustrated in the drawings,

the'upper end of the rod 68 is threaded into the wedge 80 so that the wedge may be adengaging and pressing together the marjusted longitudinally of the rod. The clamp connection between the arm 67 and the rock shaft '66 enables the arms 65 and 67 to be relatively adjusted angularly. When narrow or pointed toed shoes are to be operated upon the wedge 80 is adjusted on the treadle rod 68 and the arms 65 and 67 are relativelyadthe engagement of the arm 65 with the pin 64 to engage the clutch and the upward movement of the wedge 80 is thereby limited beforeth'e latter wedge is-eng'aged with the rolls 82, When round toed shoes are to be operated upon the wedge 80 is adjusted on therod 68 and the arms 65 and 67 are rela tively readjusted so that the wedge 80 will engage the rolls 82 swing thejcarriers l0 outwardlyto separate the supports 2 before V same, and means for actuating said devices the wedge 56 is actuated by the engagement ofthe arm 65 with the pin 64 to engage the clutch. The separation of the supports 2 1" enables the shoe to be inserted between the same in position to start the operation before the machine is started,

The above described machine is adapted 'for use in the applicatio'nof soles to shoe projecting beyond the upper is formed by -a-welt or by the projecting margin ofan intermediate sole, and in'the manufacture of 'so called stitched down shoes in which this projectings'ole portion of the shoe is formed by a flange on the upper.
